Sharon, not sure the question. I think you could create a thrird column to
check and either put the average or the number you want then average. so for
the first line, =if(round(a1,0)=b1,a1) would put 2.3 in column 3 only if the
rounded amount (2) = 1. I did not see any matches in column 1 and 2 which is
why I am confused
